Overview of FLEX I/O and your Analog
Modules
Chapter Objectives
In this chapter, we tell you about:
•
what the FLEX I/O system is and what it contains
•
types of FLEX I/O analog modules
•
how FLEX I/O analog modules communicate with
programmable controllers
•
the features of your analog modules
The FLEX I/O System
FLEX I/O is a small, modular I/O system for distributed applications
that performs all of the functions of rack-based I/O. The FLEX I/O
system contains the following components shown in Figure 1.1:
Figure 1.1
•
adapter/power supply – powers the internal logic for as many as
eight I/O modules
•
terminal base – contains a terminal strip to terminate wiring for
two- or three-wire devices
•
I/O module – contains the bus interface and circuitry needed to
perform specific functions related to your application
